PuTTY wish terminfo

summary: Maintain a terminfo for PuTTY's terminal emulatorclass: wish: This is a request for an enhancement.difficulty: fun: Just needs tuits, and not many of them.priority: medium: This should be fixed one day.

It would be nice to maintain our own terminfo/termcap description of
the terminal emulated by PuTTY, as an alternative to having PuTTY
claim to be an xterm and hoping everybody's xterms behave similarly.
